Hi Xavier,

Sr >>> Nomfich is an abreviation and does not do any parameter 

substitution, "Nomfich" is taken literally. Therefore, you want to use 

the full command: PutAppend.



Concerning the non-apearing Plot, in version 6+7 graphics is treated 

equal to text. You must wrap "Print" around the Plot.

hope this helps, Daniel
